My Windows 10 'winload.efi' became corrupted and I opted to clean install using the Windows media creator tool to create a bootable USB. Upon booting from USB, I chose custom install and proceeded to delete down to one partition followed by a format of that partition (as I had done for other clean install of windows 7/XP). Unfortunately, there was an error thrown and Windows could not install, leaving me stranded without an OS. From a mac, I created another bootable USB from a complete Windows 10 iso file.
The Windows installer boots, unfortunately when I attempt to delete or format any of the partitions:
{
Drive 0 Partition 1: Recovery,
Drive 0 Partition 2: System,
Drive 0 Partition 3: MSR,
Drive 0 Partition 4: Primary,
}
the installer throws the following errors:
"We couldn't delete the selected partition. [Error: 0x80070001]"
"We couldn't format the selected partition. [Error: 0x80070057]"
I have tried 'shift + F10' as recommended elsewhere to bring up a command prompt but not such prompt appears (presumably because I don't have a functioning OS anymore).
What can I do without an OS? How can I format the partitions and install from the bootable USB? Can this be done from BIOS? I'm working from a Lenovo T580 laptop. Thank You.
